# 20200113 bkw:
# - Take over maintenance.
# - Add man page and privacy patch, BUILD=2.
# - Get rid of "shared" from make command. We weren't installing the
#   shared library anyway, despite the comment above from Daniel
#   Jordan. The only thing that lists astyle as a dependency is ebe,
#   and that's a runtime dep (it executes the astyle command, doesn't
#   link the shared lib). If someone needs the shared lib, I can add
#   it to the build, but for now I'm leaving it alone because the
#   .so isn't versioned (upgrades may cause breakage).
# - Simplify and tweak the script.
